lssevdiskcopy
Use the lssevdiskcopy command to list the thin-provisioned copies of the specified volumes.
Syntax
>>-lssevdiskcopy-- --+----------+-- --+----------+-- -----------> '- -nohdr -' '- -bytes -' >--+-----------------------+-- --+---------------+-- -----------> '- -delim -- delimiter -' '- -copy -- id -' >--+-----------------+--+------------+------------------------->< '- -filtervalue? -' +-vdisk_name-+ '-vdisk_id---'
Parameters
- -nohdr
- (Optional) By default, headings are displayed for each column
of data in a concise style view, and for each item of data in a detailed
style view. The -nohdr parameter suppresses the
display of these headings.Note: If there is no data to be displayed, headings are not displayed.
- -bytes
- (Optional) Displays all capacities as bytes. Capacity values displayed in units other than bytes might be rounded.
- -delim delimiter
- (Optional) By default in a concise view, all columns of data are space-separated. The width of each column is set to the maximum possible width of each item of data. In a detailed view, each item of data has its own row, and if the headers are displayed, the data is separated from the header by a space. The -delim parameter overrides this behavior. Valid input for the -delim parameter is a one-byte character. If you enter -delim : on the command line, the colon character (:) separates all items of data in a concise view; for example, the spacing of columns does not occur. In a detailed view, the data is separated from its header by the specified delimiter.
- -copy id
- (Optional) Specifies the volume copy to list thin-provisioned copies for. You must specify a vdisk_name | vdisk_id value with this parameter.
- -filtervalue?
- (Optional) Displays a list of valid filter attributes. The following
filters for the lssevdiskcopy command are valid:
- mdisk_grp_id
- mdisk_grp_name
- overallocation
- autoexpand
- grainsize
- vdisk_name | vdisk_id
- (Optional) Specifies the volume name or ID to list thin-provisioned copies for. You must specify this parameter last on the command line. If you do not enter this parameter, the command lists all thin-provisioned copies in the clustered system.
Description
The lssevdiskcopy command lists all thin-provisioned copies of the specified volume. If you do not specify a volume, the command lists all thin-provisioned volume copies in the clustered system.
The command provides a concise view of the thin-provisioned properties of the selected volume copies. Run the lsvdiskcopy command to see a concise view of the properties that are common to thin-provisioned and non-thin-provisioned volume copies. See the description of the lsvdisk command for a description of the fields that are shown in the view.
The command returns values for the following volume copy attributes:
- copy_id
- Indicates a system-assigned identifier for the volume copy. The value can be 0 or 1.
- status
- Indicates the system status. The value can be online or offline. A copy is offline if all nodes cannot access the storage pool that contains the copy.
- sync
- Indicates whether the volume copy is synchronized.
- auto_delete
- Indicates the primary copy is deleted once the secondary copy is synchronized. The values are yes or no.
- primary
- Indicates whether the voume copy is the primary copy. A volume has exactly one primary copy. The value can be yes or no.
- mdiskgrp_id
- Indicates the ID of the storage pool that the volume copy belongs to.
- mdiskgrp_name
- Indicates the name of the storage pool that the volume copy belongs to.
- type
- Indicates the virtualization type of the volume. The value can be striped, sequential or image.
- mdisk_id
- Indicates the MDisk ID that is used for sequential and image mode volumes.
- mdisk_name
- Indicates the MDisk name that is used for sequential and image mode volumes.
- fast_write_state
- Indicates the cache state of the volume copy. The value can be empty, not_empty, corrupt, or repairing. The value is always empty for non-thin-provisioned copies. A cache state of corrupt indicates that the volume is thin-provisioned and requires repair that is initiated by a recovervdisk command or the repairsevdiskcopy command.
- used_capacity
- Indicates the portion of real_capacity that is being used to store data. For non-thin-provisioned copies, this value is the same as the volume capacity. If the volume copy is thin-provisioned, the value increases from zero to the real_capacity value as more of the volume is written to.
- real_capacity
- Indicates the amount of physical storage that is allocated from an storage pool to this volume copy. If the volume copy is not thin-provisioned, the value is the same as the volume capacity. If the volume copy is thin-provisioned, the value can be different.
- free_capacity
- Indicates the difference between the real_capacity and used_capacity values.
- overallocation
- Expressed as a percentage, indicates the ratio of volume capacity to real_capacity values. This value is always 100 for non-thin-provisioned volumes.
- autoexpand
- Indicates whether autoexpand is enabled on a thin-provisioned volume. The value can be on or off.
- warning
- Expressed as a percentage, for thin-provisioned volume copies only, indicates that a warning is generated when the ratio of used_capacity to volume capacity reaches the specified level.
- grainsize
- For thin-provisioned volume copies, indicates the
grain size chosen for the volume copy when it was created. Remember: This field is always blank for compressed volume copies.
- se_copy
- Indicates if the copy is thin-provisioned. The value can be yes or no.
- easy_tier
- Indicates whether Easy Tier® is
permitted to manage the pool. Note:
- If easy_tier is on, then easy_tier_status can take on any value.
- if easy_tier is off, then easy_tier_status is measured or inactive.
- easy_tier_status
- Indicates which Easy Tier functions are
active for the volume copy:
- active indicates a pool is being managed by Easy Tier to provide tier management performance-based pool balancing. For example, extents of this volume copy can be moved for performance (automatic data placement).
- inactive indicates that no Easy Tier function is active. Note: If Easy Tier is disabled because a node in the system does not have the required 8 GB RAM, the easy_tier_status is inactive.
- measured indicates that statistics are being gathered for this volume copy, but no extents are moved.
- balanced indicates a pool is being managed by Easy Tier to provide performance-based pool balancing (for example, extents can be moved).

- When the volume copy status is inactive, no Easy Tier(tm) functions are enabled for that volume copy.
- When the volume copy status is measured, the Easy Tier(tm) function collects usage statistics for the volume but automatic data placement is not active.
- When the volume copy status is balanced, the Easy Tier(tm) function enables performance-based pool balancing for that volume copy.
- When the volume copy status is active, the Easy Tier(tm) function operates in automatic data placement mode for that volume.
- The default Easy Tier(tm) setting for a storage pool is auto, and the default Easy Tier(tm) setting for a volume copy is on. This means that Easy Tier(tm) functions except pool performance balancing are disabled for storage pools with a single tier, and that automatic data placement mode are enabled for all striped volume copies in a storage pool with two or more tiers.
- tier
- Indicates which tier information is being reported:
- ssd
- nearline
- enterprise (the default value for newly discovered or external volume)
- tier_capacity
- Indicates the total MDisk capacity assigned
to the volume in the tier. Note: For thin-provisioned copies, the capacity by tier will be the real capacity.
- compressed_copy
- Indicates whether or not the volume copy is compressed.
- uncompressed_used_capacity
- For compressed volumes, indicates the amount of data written to the volume before compression.
- parent_mdisk_grp_id
- Indicates the physical storage pool id that the volume extents are actually allocated from. This is a numeric string (between 0 and 127 characters) or blank.
- parent_mdisk_grp_name
- Indicates the physical storage pool name that the volume extents are actually allocated from. This is an alphanumeric string (between 1 and 63 characters) or blank.
